摘    要:设计并实现一个基于领域知识的个性化旅游智能语义检索系统,给出系统的总体框架和具体功能实现。采用领域本体技术实现对旅游领域知识的建模,构建领域知识库,并将查询扩展和语义推理技术应用于基于本体的信息搜索过程中。根据用户的浏览行为和个人偏好,建立用户兴趣模型,可实现个性化的信息搜索。研究结果表明:基于领域本体知识库的语义层面的旅游信息搜索具有比传统搜索引擎更好的语义推理查询能力。

Abstract: A personalized tourism intelligent semantic retrieval system based on domain ontology was studied and designed, and the system general framework and implementation of system functions were given. The domain ontology technology was applied to realize the modeling of tourism domain knowledge, the domain knowledge base was established, and the technologies of query expansion and semantic reasoning to the information searching process based on ontology were also applied in the system. Furthermore, User’s interest model was established according to the tourists’ browsing behavior and personal preferences. The results show that the information retrieval on the level of semantic based on domain ontology knowledge base owns better semantic reasoning ability than that of the traditional search engine.
